Several critical problems

The app itself works well in theory and Ive used it all year until it was all wiped out when the 5.1 iOS update was released. Developer has acknowledged this issue, and recommends backing up often, but the backup doesnt work (generates a blank e-mail). There are other bugs that tend to wipe out attendance. Cannot find any link to e-mail developer to ask questions.
